Unokukhetha njani phakathi kweempompo ezithe tye nezithe nkqo kunye neenkqubo zamanzi omlilo wemibhobho?
Impompo yamanzi omliloIingqwalasela
Impompo ye-centrifugal efanelekileyo kwizicelo zamanzi omlilo kufuneka ibe ne-curve yokusebenza ethe tyaba.Impompo enjalo ilingana neyona mfuno inkulu yomlilo omkhulu kwisityalo.Oku kudla ngokuguqulela kumlilo omkhulu kwiyunithi enkulu yesityalo.Oku kuchazwa ngumthamo olinganisiweyo kunye nentloko elinganisiweyo yeseti yempompo.Ukongezelela, umpompo wamanzi omlilo kufuneka ubonise amandla okuhamba kwamanzi amakhulu kune-150% yomthamo wayo olinganisiweyo ngaphezu kwe-65% yentloko yayo elinganisiweyo (uxinzelelo lokukhutshwa).Enyanisweni, iimpompo zamanzi omlilo ezikhethiweyo zidlula amaxabiso akhankanywe ngasentla.Kubekho iimpompo zamanzi omlilo ezininzi ezikhethwe ngokufanelekileyo kunye neegophe ezithe tyaba ezinokubonelela ngaphezu kwe-180% (okanye nokuba yi-200%) yomthamo olinganisiweyo entloko kunye ne-70% yentloko epheleleyo.
Iitanki ezimbini ukuya kwezine zamanzi omlilo kufuneka zibonelelwe apho umthombo osisiseko wokubonelela ngamanzi omlilo ukhoyo.Umgaqo ofanayo uyasebenza kwiimpompo.Iimpompo zamanzi zomlilo ezimbini ukuya kwezine kufuneka zibonelelwe.Ulungiselelo oluqhelekileyo lu:
● iimpompo zamanzi zombane eziqhutywa ngemoto (enye isebenza kunye nenye yokulinda)
● iimpompo zamanzi zomlilo ezimbini eziqhutywa yi-injini ye-diesel (enye isebenza kunye nenye yokulinda)
Omnye umngeni kukuba iimpompo zamanzi omlilo zisenokungasebenzi ixesha elide.Nangona kunjalo, ngexesha lomlilo, ngamnye kufuneka aqaliswe ngokukhawuleza kwaye aqhubeke nokusebenza de umlilo ucinywe.Ngoko ke, imimiselo ethile iyadingeka, kwaye ipompo nganye kufuneka ihlolwe ngamaxesha ukuqinisekisa ukuqala ngokukhawuleza kunye nokusebenza okuthembekileyo.
Iimpompo ezithe tye vs. Iimpompo ezithe nkqo
Iimpompo ze-centrifugal ezithe tyaba luhlobo olukhethwa ngabasebenzisi abaninzi lwempompo yamanzi yomlilo.Esinye isizathu soku kukushukuma okuphezulu kunye nesakhiwo soomatshini esinokuba sesichengeni seempompo ezinkulu ezithe nkqo.Nangona kunjalo, iimpompo ezithe nkqo, ngakumbi iimpompo zohlobo lwe-injini ethe nkqo, ngamanye amaxesha zisetyenziswa njengeempompo zamanzi omlilo.Kwiimeko apho unikezelo lwamanzi lubekwe ngaphantsi kwe-discharge centerline ye-flange, kwaye uxinzelelo lungonelanga ukufumana amanzi kumpompo wamanzi omlilo, i-vertical-shaft turbine-type pump seti ingasetyenziswa.Oku kusebenza ngokukodwa xa amanzi asuka kumachibi, amachibi, amaqula, okanye ulwandle aya kusetyenziswa njengamanzi omlilo (njengowona mthombo okanye ugcino).
Kwiimpompo ezithe nkqo, ukucwiliswa kweebhotile zempompo kukulungelelaniswa okufanelekileyo kokusebenza okuthembekileyo kompompo wamanzi omlilo.Icala lokufunxa lempompo ethe nkqo kufuneka libekwe nzulu emanzini, kwaye ukuntywila kwe-impeller yesibini ukusuka ezantsi kwesitya sempompo kufuneka kube ngaphezu kweemitha ezi-3 xa impompo iqhutywa kwinqanaba eliphezulu lokuhamba okunokwenzeka.Ngokucacileyo, olu lulungelelwaniso olufanelekileyo, kwaye iinkcukacha zokugqibela kunye nokuntywiliselwa kufuneka kuchazwe kwimeko nganye, emva kokubonisana nomenzi wempompo, amagunya omlilo asekuhlaleni kunye nabanye abachaphazelekayo.
Kukho iimeko ezininzi zokungcangcazela okuphezulu kwiimpompo zamanzi zomlilo ezithe nkqo.Ke ngoko, izifundo eziguquguqukayo ngononophelo kunye neziqinisekiso ziyimfuneko.Oku kufuneka kwenziwe kuzo zonke iinkalo zokuziphatha okuguquguqukayo.
